Application led February 5, 1914,

To all whom it may concern.'

Be it known that 1, RICHARD L; LEAGH, a citizen of the United States,and a resident of Honolulu, in the county of Honolulu -and Territory ofHawaii, have invented a new. and useful Vehicle-Tire, of which thefollowing is a description. My improved vehicle tire is of the generaltype disclosed 'in my Patent No. 1,077,085, dated oct. seth', i913.,

Among the various 'objects of myfpresent invention are .the following:1.. '1`o enable the tire casing to be hooked tothe roll of the wheelrim, fromthe outside., so as tol render the tire casing and the tireboth readily detachable from the rim, and also to enable the tire todrop off the rim or atleast to be easily detached therefrom, when thetire is deflated. 1I. To give .the plates ofthe tire casing such form asto enable them to practically cover all portions of the tire whichotherwise would be'exposed. 111. To provide anti-skidding lugs ofimproved form,

and to provide improved means for securing these lugs'in position andfor holding them to the casing as well as to the tire. 1V. To give therubber member of the tire such form that its outer surface is irregularin order to lit the different shaped members ofv the tire casing'` theinner portion of the'rubber member of the tire being smooth. V.

vTo improve the resistance of the tire and its casing as againstpunotures and abrasions,

and to provide improved means for enabling thegmetalli'c portions of'thetire casing to take up and sustain the pressure of the tire due toinflation thereof.

Reference is made to the accompanying drawings forming a part of thisspecification, and in-which like lletters' indicate like parts.v

' One of the spokes is shown at 9, and mounted upon the same is anannulaifelly 10. Disposed upon .opposite sides of this `felly are twoflat rings 11, held in position and clamped against the felly by bolts,one of which is shown at 12. This bolt is providedrwith a head 13 and isfitted with a nut 14. Each ring 1'1 is provided with an outwardly turnedor flaring portion 15, and between thefrings 11 and engaging the outerperipheral surface of the felly 10 is a lining ring 16.

The inner tube ofthe tire is shown at 17, and the liber jacket of thetire appears at 18. Secured `to this fiber jacket and partiallyencircling the saine is the tire covering 19, which is a member made ofrubber. The flaring portions 15 of therings 11 are each provided withslots 15a and partially bound- 1 ing these slots are two supportingrings 20, secured firmly tothe outer peripheral edges ofthe daringportions 15, and constituting practically parts of the' rim roll of thewheel. Located in close proximity to each ring 2O are a. number of armorplates 21, each pro\ vided at its bottom with straight edges 22, 'andfurther provided with a tongue 23, this tongue being bent into proximateC-shape and thus formed intoA a hook, as may be understood from Fig. 1,and adapted to fit into any one of the slots 15a. The armor plate 21 isfurther provided with a pair of necks 24, each carrying a ball 25,integral with it.l Located adjacent the lplates 21 and alternatedtherewith are a number of other plates 26, each provided with straightedges or shoulders 27, and with a substantially C- shaped hook 28precisely like the hook 23 above described. Each plate 2.6 is furtherprovided with a single neck 29 carrying ball 30, these parts beingintegral.

A number of other armor plates 81, 311?, are provided, these platesbeing exactly alike except asto size. That is to say, the plates 31aareslightly larger than thev plates 31, and the'plates 31b .are slightlylarger than. the

plates 31, so that the various plates employed increase in size,reckon-ing from the rimof the Iwheelto the outer peripheral surface, ortread surface of the tire. This difference in the size of the plates 31,31",

ico

is merely to compensate for differences in the diameter of differentportions of the tire. Each of the plates 31 is provided with. threenecks 32 and with concave vshoulders 34 of arcuate form, there being-two of these shoulders upon opposite sides of each neck 32. Each of theplates 31a, 31h, is further provided 1with three straight edges 35, eachof' these edges being disposed between two of the arcuate edges4 34, aswill be understood.

from Fig. 3. I use a number'of metallic bearing disks 36 'which arepartially sunken into the rubber member jacket 19. Each of these bearing disks is provided centrally with a prof.

jecting stern 37, this stem having a central openingA 38. Each disk '36is further provided with a cavity 39 of substantiallyhemispherical-form, and with apassage 40 having a semi-cylindrical formand merging into the cavity 39. A separate disk 41 is pro#v Avided withanumber ofl -semi-cylindrical passages 42 and with a number ofsubstantially helnispherical cavities 43 into which the passages 42merge, as shown in fFig.. 6.. The disk 41 is further provided with abellf. shaped aperture 43", through which the stein 37 ofthe disk 36-may be extended. 'Afteifj the stem -37 is thus extended through theaperture 43a., the stem 37 is spread or clenched as shown at 37a in Fig.6, the opening 38 of the stern 'being thus enlarged, las

' indicated at 38a.

The various parts are assembled asliollows: Thedisks 36 are spaced apartby suitabledistances and the varius plates 21, 26,

31, 31, and 31" 'are arranged relatively to each other, as indicated inFigs 2 and 3, so

that the various balls 25, 30,' v33 are `par- Vtially inserted withinthe various cavities 39. A- number of disks. 41 equal to the number ofdisks 36 are next placedin position, so that the upper portions of thevarious balls 25, 30,33, extend into the liemispherical .are at the'same time fitted into the semilcylindrical passages 40, 42, Vthe llatterbrought into juxtaposition, or in other Words caused to mate each other.In arranging are disposed near the outer peripheral or tread surface ofthe tire, as above indicated.

hooks 23, 28 are brought into the slots 15',-

The stems 37 being next clenched,- as indicated in Fig. 5, each disk 41-is secured rigidly,l to -its mating disk 36, andthe tire armorfas .awhole is now-complete. The tire 'as a whole being now complete, thevarious and hooked upon the rings 20. The tire being nowv iniiated inthe usual manner, the

'stenson of the tire causes thehooks 23 and 28 to grip the rings 2O verytightly. If, however, the tire becomes deflated, the hooks 23 and 28become disconnectedl from the .rings 20, so that the tire practicallyfalls cavities 43. The various necks'24, 29, 32,v

the plates`31, 31,, 31", the larger size plates.

4I claim as new and desire to secure by Let-v ters Patent is as follows:

1.*In a tire, the combination of a tubular portion, a rubber iacketpartly encircling the same,disks sunken slightly into said rubber jacket.and provided with cavities of substantially hemispherical form, andwith passages of substantially semi-cylindrical form, said passages.'merging into said cavities, plates provided with necks for4 extendingthrough said passages and with balls carried by said necks for fittinginto said cavities,` and other disks connected with' said firstlmentioned disks and. provided with bearing portions for itting uponsaid necks and said balls.` x

`2.In a tire armor, a covering of rubber `partially encircling a tire, aplurality of anti-skid members spaced apart and each partially sunken inthe rubber covering, a

plurality of plates'disposed about the antiskid members, meansI formingball and socket connections between'the said plates and the anti-skidmembers, and means. lfor connecting sundry of said platesy with theWheel rim to hold the armor in position on the tire. y.'

3. In atire armor, theigcombination of a' plurality of anti-skid memberseach being substantially circularin form andprovided.

with sockets and with passages merging into 'said sockets, and apluralityof plates each provided with a member extending' into one ofsaid sockets and with, a vneck extending through one of saidpassages,'each of said plates being provided with a plurality ofstraight edges and withv .a plurality of edges. I

45.111 a tire armor, the comblnation vof a 'pair of disks connectedtogether bya centrallyI disposed member 'carried 1by one of said disksand engaging the-other, said disks together being provided with socketsarranged in a circle and with radially dlsposed passages merging intosaid sockets, and a plurality of plates arranged around the saidv disksfand each comprising a body portion having-a curved edge correspondingin shape to the* periphery of the disks, the plates being'each providedwith a neckvextending from the body.' portion through one of saidpassages and with' a sphericalmember carcurved edges ofarcuateform,'said curved v edges being located between said straight l ried bysaid neck and jfitting into one of said of anti-skid members each havinga disk partially sunken in the rubber covering and '10 a mating diskadapted to be secured to the and an armor comprising a plurality irstdisk, a plurality of' plates disposed about the anti-skid members, meansformin ball and socket connections between the sai plates and theanti-skid members, and means lfor securing the armor tothe Wheel rim.
